ROLLING WINDOW-SCREEN.

SPECIFICATION forming part ofV Letters Patent No. 267,618, datedNovember 14, 1882. Application tiled September 22, 1882. (No model.)

To all fr0/tom it may concern:

Be it known that I, THOMAS TRIBE, a citizen of the United States,residing at Colorado Springs, in the county of El Paso and Stateot'Colorado, have invented a new and useful Rolling Window-Screen, of whichthe following is a specification, reference being had to theaccompanying drawings.

Figure l is a perspective View Ot' a windowframe having my improvedscreen and shade, part having` been broken away in order to show theconstruction more clearly. Fig. 2 is a vertical sectional View. Fig. 3is a` horizon- 'ta-l sectional view on the linex, Fig. 2. Fig. 4 is ahorizontal sectional view 011 the lineyy, Fig. 2. Fig. 5` is a frontview, parts having been broken away. Fig. 6 is a vertical svetional viewillustrating a modification in the arrangement of the screen. Fig. 7 isa detail view ofthe lower end'of the screen; and Fig. Sis a detail Viewof the lower end of the shade.

Corresponding parts in the several figures are denoted by like lettersof reference.

This invent ion relates to rolling screens and shades for windows; andit consists in certain im provcments in the construction and arrangementof thetsame, which will 'be hereinafter fully described, and`particularly pointed out in the claims.

` In the drawings hereto annexed, A represents an ordinary window-frame,B the upper and C the lower sash.`

The screen I), to which my invention principally relates, is made of anysuitable netting, and is attached to and adapted to be wound upon auordinary spring-roller, E, inthe construction ot' which no novelty isclaimed. If

. the window-frame to which my invention is appplied has no insideblinds, l arrange the brackets or bearings F for said roller, as shownin Fig. 6, directly infront of the inner sashbead; but when, on accountof the use of inside blinds, this is not practicable, I secure at theupper end of thewindow-frame, between the inner and middle beads, blocksG, ilushwithsaid beads, to which the roller-brackets Fare then secured.These blocks, whichneed not exceed 'a'few inches in length, do notmaterially interfere with the operation of the lower. or inner sash, theweight-cords of which are accommodated in grooves H inthe inner.

lare thereby kept stretched and taut.

rectly above the screen-roller E, as shown in the drawings.

To the sidesof the window-frame or oi" the inner beads, K, as the casemaybe,are secured vertical guide-strips L, having recesses or pockets Mand narrow slits N, to receive and guide the edges of the screen andshade,which In order to retain them in the pockets M, and to preventtheir sliding out through slit N, the said screen and shade are providedwith cords O, parallel to and at a short distance from the edges, said"cords being threaded through the fabric, as clearly shown in Figs. 7and S ofthe posite sides. I would have it understood that `thisconstruction is an important feature ot' my in ventiou, and isessentially different from an ordinary bound or corded edge, formed byinclosing a cord in a hem of the fabric. Such construction would preventthe fabric from winding smoothly and perfectly upon the roller, andrender the device practically inoperative and valueless, while by myimprovement a perfect and successful operation is insured. It will benoticed that thepockets M are amplylarge to accommodate any surplus edgeof the fabric outside the cord O.

The sides of the window-frame (or the inner beads) just belowthescreenrollerare connected by a pair ot' transverse guide-strips, l)Q, between which the shade passes. The outer strip, Q, is connected withthe top of the window-frame by a boxing, It, of wire-netting or othersuitable material,thus making a tight joint, which absolutely preventsthe admission of insects at this point.

The screen D has at its lower edgea Slat, S,

of such lengthA as to fit nicely between the edges of the screen, theirupper ends being se- `IOO W W are elasticstrips arranged near the.

cured to the roller E and theirlower ends to slat S. These strips haveseveral important functions-namely, to assist in holding the fabric ofthe screen stretched and taut to brace it against the wind or otherpressureand to space it as it is being wound upon the roller, thusadording room between the layers for the cords O, thus depriving thelatter ot' any tendency to cause the screen to wind uneven'ly. Beingelastic, the strips W rwill stretch in the 4act of windin g, thuspacking the screen fabric nicely and closely upon the roller.

The shade I is, like the screen, provided at its lower edge with a slat,X, havinglaterallyprojecting guide-plates Y. Elastic strips may also beused in connection with the shade; but I do not deem it essential.

The screen-strip S is provided at both ends with suitably -constructedspring bolts or catches Z, projecting so as to engage notches A atvarious points in the guide strips or rails L. The inner ends of thebolts Z are connected bya cord, B,which is guided throughsnitably-located screw-eyes C', so as to form a central pendent loop,D', by means of which the screen may be adjusted and manipulated. Thusby pulling the loop D the bolts or catches are released from thenotches. By continuing to pull the screen may be lowered to the desiredpoint, while by raising the hand the screen will be wound upon theroller. This catch or bolt mechanism is an important feature of myinvention, as by it the screen-Slat S may be adjusted closely in contactwith the window-sill, and may be readily raised or lowered by simplymanipulating the cord-loop D.

When my improved window-screen is used separate from the shade Isubstitute guidestrips L having a single pocket and slit, M'N.`

In other respects the construction will be the Same.

My invention, aswill be seen, is applicable screens. All of this I donot claim; but

I claim and desire to secure by Letters Patent of the United States- 1.A rolling screen or shade having cords threaded through the fabric ofwhich it is conlposed, near the edges, substantially as setforth.

2. The combination, with a rolling screen, of elastic strips arrangednear its edges, and attached to the roller and bottom slat,substantially as set forth. y

3. The combination, with a rolling screen or shade having cords threadedthrough the fabric ot' which it is composed, near the edges, of elasticstrips arranged near said cords, and having their upper and lower endsattached to the roller and bottom slat, respectively,.as set forth..

4. The combination of the window-frame,the spring-roller E, the screenD, having cords 0 threaded through its fabric near the edges, and theguidestrips L, having pockets M and slits` N, as set forth.

5. The combination of the spring-roller, the

rolling screen, the transverse guide-strips P Q, and the Wirenetting boxR, as and for the purpose set forth. 6. The combination, with thewindow-frame, of the blocks G, having grooves H, the bearings orbrackets F, and the screen-roller, substantially as set forth.

7. The combination ofthe 'rolling screen, the cords threadedlongitudinally through the same, and the bottom slat havinglaterallyprojecting plates to which the lower ends of said cords aresecured, as set forth.
